Found a pretty cool Golang library which is like the Golang equivalent of `dig`. https://github.com/lixiangzhong/dnsutil

@ctOS namesys has like a 256 level recursion so when I pass in `media.ctrl.blog` it will find the dnslink entry but when I pass in `_dnslink.media.ctrl.blog` it complains about it being an invalid domain name. 

With the `dnsutil` package though I'm able to parse through `_dnslink.media.ctrl.blog`.

Yea I'm going to use an in-memory cache for that
